摘　　要：讨论了一类具有ＨｏｌｉｎｇⅡ类功能反应且两种群均有密度制约项的捕食系统．证明了该系统在第一象限内至少可以出现１２种不同的轨线分布，而且不难构造出它们的具体例子．We discussed a class of pradator prey model with Holling Ⅱ type functional response,in which both of the two species are density dependent,and proved that this system can exist of least twelve different types of orbit distribution in first quadrant,and it is easy to construct their contrete examples.
